C mini-contest
Go guess, what's behaviour of this code:
int foo() {
while (0) while (1) while (2) ;
}
and this
int foo() {
while (2) while (1) while (0) ;
}
Both are valid C constructs, of course.
PS: Question itself is rather trivial, but at least to me it demonstrates important aspects of how dangerous implicit boundaries of C statements could be.
PPS: actually code which inspired me on this example was this comparison:
while (1) { } while (0);
do { } while (0);
which looking structurally same in fact are parsed completely differently
